Detailed Product Description

The multi-story steel frame is a structural system primarily composed of steel load-bearing components, widely used in buildings ranging from 6 to 40 floors (20-150 meters). Known for lightweight yet high-strength properties, rapid construction, and excellent seismic performance, it represents a modern industrialized building solution.

Component Technical Description
Steel Columns Box-section or H-section (400×400 to 800×800 mm), slenderness ratio ≤80.
Floor System Composite slabs (100-150 mm thick) or steel bar truss decks (span 3-6 m).
Protection Epoxy zinc-rich primer + fireproof coatings (1-3 hours resistance).
Construction Factory prefabrication with ±2 mm/6 m tolerance.

Frequently Asked Questions
What is the estimated service life of your steel structures?
Our steel frame structures are designed for long-term durability, with a service life exceeding 50 years under standard maintenance conditions.
How does the structure perform against earthquakes and high winds?
The system is engineered for Grade 8 seismic resistance and Wind Resistance Rating 12, utilizing ductile design principles and high-strength materials.
Is the steel treated for corrosion and fire protection?
Yes, we provide hot-dip galvanizing or epoxy zinc-rich priming for anti-corrosion, and intumescent or cementitious coatings for fire resistance up to 2.5 hours.
Can the design be customized for specific project requirements?
Absolutely. We offer customized structural design using PKPM and Tekla, allowing for flexible layouts and specific span requirements (6-12m standard).
What are the advantages of prefabricated steel over traditional concrete?
Prefabrication allows for 30%-50% faster construction timelines, higher precision (millimeter accuracy), and over 90% recyclability of materials.
How do you ensure quality during international shipping?
Components are secured with galvanized steel strapping and EPE pads. We use specialized containers (HC, OT, or FR) and include GPS tracking for oversized cargo.
